摘要
开孔是耐压船体舷侧不可缺少的结构,开孔后一般采用圆柱形围栏加强,围栏高度及安装尺寸依开孔半径确定。利用MSC/PATRAN软件对开孔围栏问题进行有限元分析,研究正交开孔下围栏半径、高度以及安装尺寸对开孔区域应力的影响。
Openings are indispensable structure on sides of pressure hull. Openings are usually reinforced with coaming, whose magnitude and installation size need to be determined by opening radius. In this paper, MSC/PATRAN was used to perform finite element analysis on openings with coaming reinforcement. And stress nearby opening influenced by coaming radius, magnitude and installation size was studied.
